Good, someone reads my posts.Stumpy, I believe Vitner meant 'smoking causes cancer'.
Do I remember it correctly if UK authorities has recommended parents not to let children use mobile phones?
Since epidemiological studies hasn't yet produced strong evidence for health risks the conclusion you can make is that if there is a health risk it is likely small. Going out in the sunshine will heat up your brain more than a phone will if you ask me.
And to address the original post, this study on rats doesn't indicate that RF radiation has an effect on reproduction. (Hm but measuring the rectal temperature on rats, how gross can you get?)
